Define a Product ID (legacy document)
Define Product ID in Data Sources
Select one or more attributes from your import feed to serve as a unique identifier. Services including Unique ID generator, Data Crawler, as well as auto-generated feed services such as Tracking Data, Keywords Feed use this ID to synchronize with your main feed.
Similarly for delta detection, a unique identifier enables the Productsup platform to detect new, changed, and deleted products.
If the main feed does not contain a unique identifier, you can generate one by selecting several attributes.
Productsup tracking does not use the Product ID. However, ROI management does use it.

Define a Product ID in tracking settings
Select the ID attribute that contains the data the Productsup platform should use to match tracking data on your website. Normally, this attribute is the product page pixel used for tracking.
